Abstract (en)
The tire (14) has a casing comprising an inner wall (42) for surrounding convex outer walls (34a, 34b) of a peripheral seat (22) and provided with a retaining bead (52). The bead is received in a peripheral slot (26) in the seat. A convex outer wall (44) of the casing forms a tread of the tire. The inner wall is concave so as to surmount the convex outer walls of the seat. The inner wall and the outer wall of the casing are connected by two annular borders (46, 48). The borders cover the outer walls of the seat in a direction of a hub (16), where the hub is surrounded with the seat. An independent claim is also included for a wheel rim formed of a hub surrounded with a peripheral seat.
Abstract (fr)
Un pneumatique (14) de type semi-creux comprend une enveloppe ayant un volume interne non gonflé et comportant une paroi intérieure (42) munie d'un talon de retenue (52) et une paroi extérieure (44) convexe formant la bande de roulement du pneumatique, la paroi intérieure (42) et la paroi extérieure (44) du pneumatique étant reliées par deux bordures annulaires (46, 48). La paroi intérieure (42) du pneumatique (14) est concave de manière à coiffer une paroi extérieure (34a, 34b) de forme convexe du siège périphérique (22) d'une jante (12) d'une roue, cette paroi extérieure étant munie d'une fente périphérique (36) destinée à recevoir le talon de retenue (52) du pneumatique.
